ABSTRACT
Our motivation for the last and the next clinical analog study was similar. In Chapter Two the discovery of a subtle CT scan abnormality in the temporal horn of sadists was an exciting finding. It was detected by CT scan but not by neuropsychological testing. We did not examine electroencephalograms (EEGs) which may have been informative. We wondered why 56% of sadists showed the CT scan abnormality and 44% did not. It was possible that more cases could be identified if other measures like EEG were employed. More specifically, it would be useful to demonstrate that the temporal horn in man was important in sexual behavior. Knowing this, we could examine sadists as well as other rapists to see how, and if, they differed. Unfortunately very little work has been done relating EEG or other brain measures to sexual arousal in man. So we turned to community volunteers and a clinical analog study to do some of the ground work necessary for a further study of sexually aggressive men. The next chapter examines whether there are recognizable EEG correlates of penile erection. Power Spectral analysis of the EEG during sexual arousal is reported for the first time in a controlled study.
